"Sulfur treatment" is a method that has been used in the past to suppress the leaching of alkaline components, suitable for surface treatment of glass containers. By reacting glass with sulfur compounds at high temperatures, alkaline components in the glass surface layer are selectively extracted and removed. This is expected to prevent changes in the internal liquid over time, reduce potency, and suppress the generation of flakes. This document provides a detailed explanation of the mechanisms and various test results, such as the amount of alkaline leaching when treating different types of glass containers, using charts and graphs. [Contents (excerpt)] ■ Effect of sulfur-treated glass containers on reducing alkaline component leaching ■ Mechanism of sulfur treatment ■ Amount of alkaline leaching when treating various glass containers ■ Quantification and confirmation methods for sulfate ions ■ Confirmation of sulfate ions using sulfate testing methods *For more details, please refer to the PDF document or feel free to contact us.

Are you familiar with "silicone coating" that prevents adhesion to liquid and powder containers? This document introduces silicone-coated containers, which are created by applying dimethyl silicone to glass containers and then heat curing to form a silicone film on both the inner and outer surfaces of the glass container. Silicone-coated containers possess liquid-repellent and powder-repellent properties, enhancing surface smoothness. As a result, they contribute not only to improved quality stability, product value, and safety but also to enhanced work efficiency. This document clearly explains the mechanisms of silicone-coated containers and practical examples! It is designed to be easy to read, even for beginners in silicone processing, using diagrams and photos. [Contents] - Features of silicone-coated containers - Mechanism of water repellency in silicone-coated containers - Safety of silicone-coated containers - Liquid and powder repellent states in glass bottles (aqueous solutions, suspensions, powders, freeze-dried products) You can download the document immediately from "PDF Download."

"PVC coating" refers to the process of applying a transparent polyvinyl chloride resin coating to the outer surface of glass bottles. This treatment enhances the impact resistance of the bottles, making them less prone to breakage. Additionally, even if the bottle does break, it has properties that prevent glass shards from scattering, thereby avoiding the risk of injury from glass fragments. PVC coating can also be colored. Please consult us for various applications, such as translucent or opaque options. 【Features】 ■ The processing improves the impact resistance of the bottle, making it less likely to break. ■ Prevents glass scattering in the event of breakage. ■ Excellent transparency allows for good visibility of the contents. ■ Suitable for various liquids due to the use of glass containers. ■ Can be colored according to application needs. *For more details, please feel free to contact us by phone or through our company website.
